(University of Rajshahi, 2016) Rokonuzzaman, Md.; Jahan, Syed Sarwar; Ali, Md. Shawkat
This experiment was carried to evaluate production performance, meat yield characteristics, chemical composition of meat, proximate component of supplied feed and profitability of broiler strains in different season. A total of 405 ( 135+ 135+ I 35) day-old broiler chicks were collected from the purchasing outlets of two (02) breeding hatcheries named Kazi Farms Ltd. and Aftab Farms Ltd. Rangpur, Bangladesh. The chicks were placed in an open house and were exposed in summer, rainy and winter seasons. Chicks as hatched broilers belonging to 3 strains, 45 of each strain were reared in three seasons: summer, rainy and winter having 135 to each season with 3 replications l 5 chicks per pen. They were fed ad-libitum up to 28 days to make a comparison on their production performances. In first and second weeks of age feed consumption among the broiler strains (Cobb-500 124.88gm and 457 .6 I gm; Hubbard Classic 148.8gm and 540.26gm; Arbor Acres 104.44gm and 409.62gm) differed highly significant (p<0.00 I) in summer season. Significant differences (p<0.05) were found in body weight for first and second weeks of age (Cobb-S00 181.99gm and 419.23gm; Hubbard Classic 170.17gm and 525.84gm; Arbor Acres 151.55gm and 452.00gm) in this season. FCR were also significant (p<0.05) for first and second week (Cobb-500 0.68 and 1.11; Hubbard Classic 0.87 and 1.03; Arbor Acres 0.69 and 0.91) of age in summer season. In fourth week, there were significant differences (p<0.05) in feed intake (Cobb-500 1737 .75gm; Hubbard Classic 1879.38gm; Arbor Acres 11938.95gm) among three different broiler strains in rainy season. The significant differences (p<0.05) in body weight gain between Cobb-500 (1265.89gm) and Arbor Acres ( 1408.84) were observed at fourth week age in this season. The feed conversion ratio significantly (p<0.05) affected at third weeks of age between Hubbard Classic (I .45) and Arbor Acres ( 1.33) in rainy season. In third week of age, feed consumption (Cobb-500 873.53gm; Hubbard Classic 740.90gm; Arbor Acres 692.60gm) among the strains differed highly significant (p<0.001) in winter season. There were no significant differences (p>0.05) in body weight gain among the three different broiler strains in this season. The feed conversion ratio (Cobb-500 1.39; Hubbard Classic 1.19; Arbor Acres 1.02) were affected highly significant (p<0.001) at third week of age in winter season. The dressing weight (Cobb-500 62.66; Hubbard Classic 57.42; Arbor Acres 55.59) percentage of three different broiler strains was significant (p<0.05) in summer season. In winter season there were significant differences (p<0.01) in dressing weight percentage (Cobb-500 54.59; Hubbard Classic 55.85; Arbor Acres 52.29) in three different broiler strains. The proximate component of broiler meat and supplied feed were significantly differed in different parameter. There were highly significant differences (p<0.001) were found in net profit of per kg live weight in summer and winter seasons. In rainy season the significant differences (P<0.01) were also found in net profit of per kg live weight. Hubbard Classic performed the best in summer season compared to Cobb-500 and Arbor Acres on the basis of I ive weight. Arbor Acres showed better performance in rainy and winter season in comparison with Hubbard Classic andCobb-500 on the basis of live weight. Summer and rainy season reared broiler strains were heavier than winter season. Feed conversion ratio (FCR) of Hubbard Classic and Arbor Acres were suitable in summer and winter season respectively. But Cobb-500 and Arbor Acres both were also suitable in rainy season. According to dressing percentages, Cobb-500 were performed the satisfactory result in summer season. But Hubbard Classic was also suitable in both rainy and winter season. This experiment showed the highest market price of Cobb-500, Hubbard Classic and Arbor Acres in summer and rainy season. So, more profit was found for higher growth performance. It was concluded that the productive performance and meat yield characteristics is achievable if the different broiler strains were reared to maintain the seasonal variation. Moreover, Hubbard Classic were able to show superior performance and more profitable in summer season. Finally, some recommendations were made to ensure growth performance and profitability in summer and rainy season of broiler strains in Bangladesh.

The Linux, the open source Operating System, or Linux OS, is a freely distributable, crossplatform operating system based on Unix that can be installed on PCs, laptops, net books, mobile and tablet devices, video game consoles, servers, supercomputers and more. This Linux logo was suggested by Linux Torvalds in 1996.Just like Windows XP, Windows 7, Windows 8, and Mac OS X, Linux is an operating system. Linux is also distributed under an open source license. In fact, most versions of Linux offer what is called a Live distribution – which means you run the operating system from either a CD/DVD or USB flash drive without making any changes to your hard drive. Anyone can get the full functionality without having to commit to the installation. Once you’ve tried it out, and decided you wanted to use it, you simply double-click the “Install” icon and walk through the simple installation wizard. Actually, The Large or medium organizations need a server system to maintain their complex IT infrastructure.

Spatiotemporal Analysis and Predicting Rainfall Trends in a Tropical Monsoon-Dominated Country Using Makesens and Machine Learning Techniques
(Springer Nature, 2023-08-25) Monir, Md. Moniruzzaman; Rokonuzzaman, Md.; Sarker, Subaran Chandra; Alam, Edris; Islam, Md. Kamrul; Islam, Abu Reza Md. Towfiqul
Spatiotemporal rainfall trend analysis as an indicator of climatic change provides critical information for improved water resource planning. However, the spatiotemporal changing behavior of rainfall is much less understood in a tropical monsoon-dominated country like Bangladesh. To this end, this research aims to analyze spatiotemporal variations in rainfall for the period 1980–2020 over Bangladesh at seasonal and monthly scales using MAKESENS, the Pettitt test, and innovative trend analysis. Multilayer Perception (MLP) neural network was used to predict the next 8 years' rainfall changes nationally in Bangladesh. To investigate the spatial pattern of rainfall trends, the inverse distance weighting model was adopted within the ArcGIS environment. Results show that mean annual rainfall is 2432.6 mm, of which 57.6% was recorded from July to August. The Mann–Kendall trend test reveals that 77% of stations are declining, and 23% have a rising trend in the monthly rainfall. More than 80% of stations face a declining trend from November to March and August. There is a declining trend for seasonal rainfall at 82% of stations during the pre-monsoon, 75% during the monsoon, and 100% during the post-monsoon. A significant decline trend was identified in the north-center during the pre-monsoon, the northern part during the monsoon, and the southern and northwestern portions during the post-monsoon season. Predicted rainfall by MLP till 2030 suggests that there will be little rain from November to February, and the maximum fluctuating rainfall will occur in 2025 and 2027–2029. The ECMWF ERA5 reanalysis data findings suggested that changing rainfall patterns in Bangladesh may have been driven by rising or reducing convective precipitation rates, low cloud cover, and inadequate vertically integrated moisture divergence. Given the shortage of water resources and the anticipated rise in water demand, the study's findings have some implications for managing water resources in Bangladesh.
Study on Determination of Electricity Distribution Cost of Rajshahi PBS
(Daffodil International University, 2018-12) Rokonuzzaman, Md.
Bangladesh is an energy hunger as well as other developing country. After the freedom war to get together power emergency was a standout amongst the most imperative difficulties for the government. Step by step the test turns out to be truly harder to harder to get together power emergency, particularly to get together power emergency in the rustic region. So government shaped Rural Electrification Board (REB) from Bangladesh Power Development Board (BPDB) to satisfy the power interest for town individuals. Duty rate of electrical power relies on upon transmission and dispersion cost. On the off chance that power supply expenses are high then electrical tariff rate will high and submitted negative outcome. In this paper, it takes Rajshahi PBS as my standard PBS for calculation of the 2015-2018 fiscal year. Here it gathered some essential information, for example, Energy Import, Energy Consumption, and Monthly Consumer and so forth. What's more, this paper, it quickly talks about the about of Customer class particularly Domestic level, Customer expands Energy, Energy Import point, Social and monetary effect, Power factor Penalty and so on. This Paper additionally finds that Total Distribution cost, Distribution cost per unit, Supply cost, Supply cost per unit, Total Revenue, Total Revenue Per unit, Energy Purchase cost, System loss, Surplus and so on. This paper will likewise be useful to get learning a steady power dispersion structure to meet the future power crisis of Bangladesh. Power circulation cost is an essential issue in our nation. Since power tax rate and dissemination cost are connected with our monetary development. At last, it additionally demonstrates that Rajshahi PBS is productive Palli Bidyut Samity (PBS).
